# Reviewing Code
Review the supplied diff or file and report concrete, actionable findings.
Prefer a few high-signal issues over an exhaustive list of nitpicks.
## Process
1. Read the change and infer its intent.
2. Look, in priority order, for:
- **Correctness** — logic errors, off-by-one, wrong/missing error handling,
unhandled `None`/null, race conditions, resource leaks.
- **Security** — injection, path traversal, secrets in code, unsafe
deserialization, missing authz/authn checks.
- **Tests** — untested new behavior; the specific case that would catch a bug.
- **Clarity** — naming, dead code, or duplication that will mislead the next
reader. Only if it materially hurts maintainability.
3. Skip style a linter/formatter already enforces.
## Output
For each finding, one bullet:
`- [severity] file:line — problem, then the fix in one clause.`
Use severity `blocker`, `major`, or `minor`. End with a one-line verdict:
`APPROVE`, `APPROVE WITH NITS`, or `REQUEST CHANGES`. If you find nothing
substantive, say so plainly rather than inventing issues.From matthewhand/operating-swarm, MIT.
